FACING-RING STRUCTURE FOR CYLINDER LOCKS.

Application filed October 30, 1922.

To all whom it may concern:

Be it known that I, JOHN B. Fnnrsrncnn, a citizen of the United States,and a resident of Stamford, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inFacing-Ring Structures for Cylinder Locks; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in facing or rosering structuresfor cylinder locks,-one object of the invention being to provide astructure of this character which shall embody 21 facing ring of suchmaterial as to constitute also armor means to protect the lock cylinderagainst penetration of a boring tool and also to provide simple andeflicient resilient means which shall insure a proper close connectionbetween said ring and the flanged or headed end of the lock cylinder.

\Vith this and other objects in View, the invention consists in certainnovel features as hereinafter described and pointed out in the claims.

In the accompanying drawings,-

Figure l is a front View of a facing or rose ring structure embodying myimprovements, and

Figure 2 is a sectional view illustrating the application of myinvention to the cylinder of a lock, a portion of said cylinder beingshown in elevation.

In the drawing, I have shown the body of the facing ring 1 as made in asingle piece and it will preferably be composed of steel or hardenedmetal.

The ring 1 is made in its rear face with an annular recess 2 and thebottom of this recess forms a seat for an annulus 3 of spring metal,said annulus being provided with an annular flange 4 which lies againstthe wall of the recess 2 and said annulus is held in place by projectinga portion of the metal of the ring over the edge of said annular flangei as indicated at 5.

The annulus 3 projects inwardly beyond the plane of the inner edge 6 ofthe ring 1 and is split to provide a plurality of outwardly projectingspring fingers 7 which are adapted to bear against the rear face SerialNo. 597,938.

of the flanged or headed end 8 of a lock cylinder 9 for the purpose ofinsuring a proper close connection between said lock cylinder and thefacing ring. Since the major portion of that part of the spring annuluswhich projects inwardly beyond the inner edge or face portion 6 of thefacing ring is split to form the spring fingers 7 it is desirable toreinforce those portions of said annulus which constitute the bases fromwhich said fingers project, and for this purpose the facing ring isprovided with inwardly projecting lugs 10 which overlie such baseportions (indicated at 11) as clearly shown in Figure 1.

The steel facing ring 1 may be covered by a scalp 12 of a metaldifferent from that of which the body of the ring is composed and thisscalp may be given any desired ornamental configuration.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent, is:

1. A facing ring structure, comprising a body member having an annularrecess in its rear face, an annulus of spring metal located in saidrecess and projecting inwardly beyond the same, said annulus hav ing anannular flange disposed in said recess, an edge portion of the bodymember overlying a portion of said flange to retain the annulus inplace, and spring fingers projecting forwardly from the inwardlyprojecting portion of said annulus.

2. A facing ring structure, comprising a body member having an annularrecess in its rear face, an annulus of spring metal disposed in saidrecess and projecting inwardly beyond the same, tongues integral withthe inwardly projecting portion of said annulus and projecting forwardlyfrom the same, and lugs projecting from the body of the ring anddisposed in front of those portions of the annulus which constitute thebases from which the tongues project.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
